IMPROVEMENT lN SAND-PAPER HOLDERS.

Specification describinga new and useful Improvement in Sand-Paper Holders, invented by JOHN D. GERNEZ, of the city, county, and State of New York.

Figure l is a side view of my improved sandpaper holder. Fig. 2 is a detailed vertical cross-section of the same taken through the line a? 00, Fig. 1. Fig. 3 is a detailed vertical longitudinal section of the same taken through the line I y, Fig. 2. Fig. 4 is a detailed vertical cross-section of the same taken through the line 2 2, Fig. 3.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved device for holding sand-paper while being used, which shall be so constructed as to hold the sand-paper securely, and at the same time in such away that it will not injure the fingers of the operator, and may be shifted as it becomes worn, so that all the paper may be used up; and it consists in the construction and combination of the various parts of the holder, as hereinafter more fully described.

A is the cork-block, over which the sandpaper is drawn while being used, and upon the upper side of which is placed the base of the wooden hand-piece B, the upper part of which is made cylindrical in shape, as shown in Figs. 1, 2, and 4. The upper part of the hand-piece B has a cylindrical hole formed through it to receive the roll of sand-paper, from which hole a slot leads out through the side of the base of said hand-piece, just above the cork-block A, for the sandpaper to pass through, as shown in Figs. 2 and 4. O are end plates, which are attached to the ends of the cork-block A and hand-piece B. Upon the inner side of the plates 0 are formed flanges c, which fit into the ends of the cylindrical hole and of the slot of the hand-piece B, and support said hand-piece at the same time that they form a groove or channel for the side edges of the strip of sand-paper to work in. D is a rod or shaft, which passes through the center of the cylindrical hole in the hand-piece B, and through holes in the end plates 0, which thus serve as bearings for'the said shaft D. Upon one end of the shaft D is placed a small crank or crankwheel, E, which is secured in place by a nut screwed upon the end of the said shaft, as shown in Figs. 1 and 3. Upon the other end of the shaft D is screwed a hand-nut, F, so that by turning up the said nut F the shaft D may be clamped in any position into which it may be turned. Gr represents a strip of sandpaper, one end of which is securely fastened to the shaft D, or to a strip of leather or other suitable material attached to said shaft, so that by turning the shaft D by means of the crank or crank-wheel E, the strip of sand-paper may be drawn into the cavity of the hand-piece B and wound upon the shaft D, as shown in Figs. 2 and 4. The outer end of the strip of sand-paper G is passed beneath the cork-block A and drawn above the side edge of said corkblock where it is clamped against the side edge of the base of the hand-piece B by the bar H, the ends of which are bent at right angles and are pivoted to the plates 0, as shown in Figs. 2 and 3.

By this construction, when the sand-paper upon the face of the block is worn out the clamp H is raised, the nut F is loosened, and the strip of sand-paper Gr is drawn out sufficiently to furnish a new rubbing-surface. The clamp H is then pushed down, the shaft D turned by the crank E sufficiently to draw the strip of sand-paper firmly over the face of the cork-block A, and the nut F is turned up to lock the said shaft D securely inplace. The worn-out part of the strip of sand-paper may then be torn off and the instrument is again ready for use.

Having thus described my invention, I claim as new and desire to secure by Letters Patent An improved sandpaper holder, formed by the combination of the cork-block A, recessed and slotted hand-piece B, flanged end plates 0 c, shaft D, crank or crank-wheel E, handlocking nut F, and pivoted clamp-bar H, with each other, to adapt them to receive and hold a strip of sandpaper, G, substantially as herein shown and described, and for the purpose set forth.
